What is the difference between the low dispersion flow cell and the analytical flow cell on the ACQUITY TUV and PDA Detector? - WKB1187

Article number: 1187

ENVIRONMENT

  • ACQUITY UPLC
  • ACQUITY UPLC H-Class
  • ACQUITY UPLC I-Class
  • ACQUITY TUV
  • ACQUITY PDA

ANSWER

  • The analytical flow cell has an inlet and outlet tubing ID of .005.
  • The low dispersion flow cell (standard cell for I-Class Systems) has an inlet tubing ID of .0025 and an outlet tubing ID of .0035.
  • The 500nL flow cells in the table below may be identified by their inlet and outlet tubing:
    • .005 tubing is red PEEK
    • .0025 tubing is tan (natural) PEEK

See attachment for the tubing ID differences and the volumes of the flow cells

ADDITIONAL INFORMATION

  • Low dispersion cell and the standard analytical cells have different tubing from the bulkhead connections to the cell body.
  • The lower volume tubing provides less dispersion when the detector is in series before another detector or mass spectrometer.
  • You see the primary advantage of using the low dispersion flow cell if another detector is upstream.
